WebInstead, existing algorithms assume that the dynamic model is a mixture of linear-Gaussian models, i.e. it switches randomly between different linear-Gaussian state/measurement equations. This can be understood as having discrete state variables in addition to the continuous ones. For these models, the true state posterior is a mixture of ... WebA time series can thus be framed as, e.g. the sum of a linear trend and a process that varies seasonally. At the end of the vignette, we refer to a post that illustrates this application. …
